No they aren't. They're fanatically religious about the tools they've chosen or were first introduced to. It has nothing to do with being picky.
Yeswell, that's what I meant I guess, probably chose the wrong term here.., oh and if those creative ppl are fanatically religious about their tool, then I'm God himself. ;P
I actually wonder whether the tools of the future become customizable in a way in which a tool can ape another tool in order to provide a fluent transition from one tool to another. Or maybe tools will remain to stick to their own identity in order to have an identity in the first place. Just look at tools like Logic, Cubase and Cakewalk/Sonar. Their basic ideas are pretty comparable, but it's in the details and the layout where the differences are. This may thus be responsible for the fact that for instance religious Cubase users won't move over to another tool, and vice versa. Using scripts one could expect to have tools which the user can alter its layout and even its features. Question is: will this happen, or will tools stick to a unique identity (which may well be part of the whole marketing of the product)?
